Instead, she gives a nuanced look at research and findings around the impact of screens on kids, and the role of parents in the age of the digital entertainment world, and reminds us that all we can do is our best.

She borrows and remixes Michael Pollan’s phrase about food, with a technological twist: “Enjoy screens. Not too much. Mostly with others.” I think that is good advice, even as I both see the benefits as a teacher and father, and worry about the impact of digital devices on developing brains, including my own children.

I appreciated her findings from surveying other parents about how they approach limiting screen time (something my wife and I grapple with at home with our youngest, a teenaged son) and how our difficulties are not isolated. It seems like many of us as parents are finding this a difficult world to navigate. How much screen time is too much screen time? What are the lasting effects of decisions we are making now? How can we find more balance for us and our kids?

Kamanetz looks not just at how kids use technology, but also how parents are becoming the role models for kids, and not always in good and positive ways. She explores the mommy-blogging world (something I sort of know about but not really, and I am both disheartened to see it commercialized and heartened to see there are places where good advice and caring communities exist).

The most important piece of advice — the one huge researched take-away for all parents that sticks with me — is to protect the sleep patterns of your children. No devices and no screens in bedrooms, and turn off screens an hour before bedtime. The sanctity of sleep is key to the development of a growing brain and emotional self.

In a nod to the world she is writing about, where time seems slippery and tl/dr (too long, didn’t read) is a cultural shortcut, Kamanetz even has a final chapter in which she summarizes her book into a five-minute read (sort of like a bulleted cliff notes version). You could read that, of course, but I suggest reading the entire book, and thinking about technology, our kids, ourselves and the world in a critical and constructive way. It is worth it.
